摘要:
A read/write memory 109 is provided with a memory controller 110 so as to store address management information temporarily. A non-volatile memory access unit 106 writes user data on a non-volatile memory 111 according to a write instruction. When the user data is rewritten, an address management information controller 105 causes a physical block, which is an object to which the address management information 108 is rewritten, to be a to-be-invalid block. After completion of a series of writing process, the to-be-invalid block is turned into an invalid block and the address management information in the read/write memory 109 is rewritten on the non-volatile memory 111.
